"After talking to my family, for the next 4 years i will be attending #Latech," Robertson wrote.

Rivals.com lists Robertson as the No. 17 overall player in Louisiana and No. 11 defensive player in the state.

The three-star recruit chose Tech over LSU, Houston, Oklahoma State and Texas. Tech had to fend off late offers from LSU and Texas, which both occurred in the last few weeks.

Robertson visited Tech the weekend of Jan. 13 and received an in-home visit last week with Tech coach Skip Holtz, defensive coordinator Blake Baker and recruiting coordinator Joe Sloan. Throughout the process, Robertson repeatedly mentioned how Tech's staff made him feel wanted.

He later visited Houston on Jan. 20 and LSU this past weekend.

The 5-foot-9 defensive back can play multiple positions and will have an opportunity to come in and play right away. He's drawn comparisons to former LSU star defensive back Tyrann Mathieu and regarded as one of the hidden gems in Louisiana. Like Mathieu, Robertson can return kicks and has enough quickness to play in a nickel role.

Tech is looking for help in the back end with the departure of safety Xavier Woods and cornerbacks Prince Sam and Cyril Noland-Lewis. Robertson may not have the size of Woods (5-11, 200 pounds), but Tech could use in a similar way all over the field.
